Abstract

A solid-state image pickup device including a solid-state image pickup element which is curved in a light incident direction and a curvature changing portion which changes a curvature of the solid-state image pickup element, and an optical instrument including a lens unit and a solid-state image pickup element which is curved toward the lens unit and picks up taking an image focused by the lens unit wherein the curvature changing portion changes a curvature radius of the solid-state image pickup element so that the solid-state image pickup element is curved at a first curvature in a telephoto mode and the solid-state image pickup element is curved at a second curvature larger than the first curvature in a wide-angle mode.
